centrifugal pump

Recently GN Separation & Conveying Equipment Company release new website, http://www.gnseparation.com/ , welcome to check our equipments information and industry news from our website. For the solids control equipments and drilling waste management equipments and oil sludge separation system information, pls check our website www.gnsolidscontrol.com, also you can check the working video and project news from this website.


Our major separation and conveying equipments including:
1) Decanter centrifuge for waste water treatment, mining & industrial sludge/ tailings treatment, chemical treatment. The bowl size available is 9 inch bowl, 14 inch bowl, 18 inch bowl, 22 inch bowl, 30 inch bowl with different treating capacity, and each bowl size have ratio available for 3 or 4 or 4.2. By the different requirement for the discharged solids moisture and discharged water clearance, different ratio ( bowl length / bow diameter) will be choosed, and the bowl angle is customized for different material.
2) Conveying Equipment: Screw Conveyor, Bucket Elevator for bulk material handling.


3) Transfer pump: Centrifugal pump, solids vacuum pump, screw pumps. The vacuum pump is widely used to transfer the cement, animal waste, oil sludge, drilling cuttings, drilling fluids, oil contaminated soils and other materials. It is 100% air operation pump without electricity power supply, it is ideal equipment to work in the electricity limit area. The air compressor is required to provide air supply for the vacuum pump operation. Centrifugal pump is interchangeable with world famous brand centrifugal pump installation and parts, it can be used as mixing pump, feeding pump of desander, desilter, trip pump, super charging pump, transfer pump of oil sludge. Screw pump is normally as feeding pump of decanter centrifuge and flushing pump of vertical cuttings dryer.

This week GN solids control shipped one batch of mud transfer pumps and mud agitators to Asia client. The centrifugal pumps are 100% interchangeable with world famous brand centrifugal pump, we can provide bare pump head and all the parts and the whole centrifugal pump with motor, skid, coupler, and control panel.


Features of GN centrifugal pump:
1. The impeller and pump casing is made of hard ductile iron alloy, which is abrasion resistant material and can longer the working life of the centrifugal pump. Different with the other competitors grey steel material, it is easily break.


2. The bearing is top brand bearing for reliable operation, the client do not need to repair the pump time and time and delay their operation.
3. The mechanical seal is also an important wear parts for the centrifugal pump, for better sealing and zero leakage and longer working life.
4. The mounting skid of the centrifugal pump is made from casting instead of welding to provide the reliable operation and less vibration for longer working life.


Mud agitator is one of the mixer equipment to be installed on top of the mud tank, together with tank bottom mud gun for better agitating and mixing of the drilling fluids in the mud tank, to prevent the drilling fluids to be accumulated in the tank bottom. The direct connection mud agitator design is with compact size, convenient operation, maintenance and customized agitator shaft length and impeller size for better performance.

1500 HP drilling rig solids control system is ready for shipment to India, this is not a complete solids control system, but the essential mud tank for the solids control system- shaker tank, the technical specification is as below:


1) 3 units of GNZS703F-SHBF shale shaker with 3pcs screens with composite material frame shaker screens
2) 1 unit of GNZJ703F-S2S12NF mud cleaner which is desander cone, desilter cone and under flow shale shaker which is the same model with shale shaker


3) 1 unit of horizontal vacuum degasser GNZCQ360A
4) 1 set of mud tank equipped the equipments mentioned above, the mud tank dimension is 14000 x2800x 2500mm, including the trip tank, sand trap, desander compartment, desilter compartment, degasser compartment
5) 2 units of centrifugal pump as feeding pump of desander and desilter
6) 1 unit of centrifugal pump as trip pump
7) 1 unit of mud gas separator GNZYQ1000A
8) 1 set of carbon steel material shed for sun proof, rain proof


The one mud tank design is to meet the client’s requirement to replace the old shaker tank, and the remained part of the existing solids control system is still in usage. All the necessary connection dimensions can fit with each other through good communication with clients. The explosion proof electric control system is equipped to control all the electric motors in the system and the big motors are controlled in the MCC at client’s rig site.
Features of the solids control system:

This week GN solids control shipped one unit of HDD mud recycling system and dewatering unit to Sinopec project. HDD is one of our major applications, GN equipments 4 major applications including oil & gas industry solids control system and drilling waste management system and oil sludge separation system, HDD & CBM industry mud recycling system, Piling & TBM desander unit, Industry waste water treatment.


The technical configuration is as below:
1) 3 phase cleaning mud recycling system mud tank, with containerized frame for convenient transportation, the user can put the mud tank and the frame with equipments on the trailer and move to another site from one site.
2) 1 unit of GNZS703F shale shaker as the first phase cleaning equipment, equipped with 3pcs of durable composite material shaker screens with customized API mesh screen. We produce OEM composite material shaker screens from API 20 to API 325 as per client’s requirement.


3) 1 unit of GNZJ703F-1S8N mud cleaner, with under flow shaker, desander cone and desilter cone combination unit. Equipped with 2 units of centrifugal pumps as feeding pump of desilter cone and desander cone.
When the drilling fluids temperature is over 70 degree, we will use special material hydrocyclones for longer working life.
4) Dewatering system with same dimension mud tank
5) Decanter centrifuge GNLW363C-VFD is the 4th stage cleaning to separate fine solids smaller than 15 microns. After several years working, more and more fine solids are accumulated in the tank bottom, these fine solids can not be separated by the desilter cone, then high speed decanter centrifuge is required to clean the drilling fluids, otherwise it can not be reused for drilling again.
